The present invention relates to toys and more particularly tohelicoptical toys.

An object of the present invention is to provide a toy of this characterwherein a propeller is projected upwardly from the toy upon rotation ofthe device.

Another object of this invention is toprovide a toy which may be readilyand easily manufactured and which may be so constructed as to withstandextremely hard usage.

A further object of this invention is to provide a device wherein thehandle and pivot are formed integrally so that the handle and pivot maybe constructed of a section of wire or the like.

The above and various other objects and advantages of this inventionwill in part be described and in part be understood from the followingdetailed description of the present preferred embodiment, the same beingillustrated in the accompanying drawing wherein V Figure 1 is a detailedside elevation partly as in section of a device constructed according tothe preferred embodiment of this invention; I

Figure 2 is a top plan view of the projectile member; and

Figure 3 is a fragmentary perspective view of the retaining stop meansfor the operating member.

Referring to the drawing wherein like numerals of reference designatecorrespond 1 ing parts throughout the several views, the

numerallO designates generally the handle portion of a helicoptical toyconstructed according to the preferred embodiment of this invention andwhich may be constructed of a section of wire which is provided with asubstantially elongated looped portion 11 which may be grasped in thehand.- One of the free ends of the loop member 10 may be bent into asecond loop member 12 and extended upwardly as at 13 so as to provideashaft or pivot member, the use of which will be hereinafter described.The opposite end portion of the loop 10 is preferably extended upwardlythrough the smaller loop 12 and bent in a substantially horizontal planeabout the lower end portion of the shaft or pivot mem- I ber 13 asflat14: so as to provide a base for an operating member or spool 15. a i r VThe horizontal loop14: is adapted to have V relative horizontal movementabout the shaft 13. The lower end portion. of the spool member 15 isprovided with a restricted portion 16 which is adapted to rotatably seaton the upper edge portion of the loop 14, andan annular groove 17 isinterposed between the .re-' stricted member 16 and the lower endportion ofthespool 15. The horizontal loop 1a is preferably extendedupwardly in a substantiallyvertical plane, and the free end'of the wireis bent'inwardly 'at at 18 so. as to provide a stop which will looselyengage in the groove 17 and not only prevent'thespool 15 frommovingupwardly onthe shaft 13 but when the loop 11 has been squeezed'bythe hand, the horizontal base sectionld will move laterally so as ,tocause the f'reejend of the stop member 18 to engage the spool so as toprea vent turning thereof on the shaft 13. a

The spool member 15 isprovided an- 5a opening 19 which is adapted toextend substantialy horizontally through the spool and in which aflexible member 20 may be mounted andwound around the spool, the innerend of the flexible member being rovided with a knot or enlarged portion21 so as'to retain the flexible member on the spool. The spool 15 isprovided'with a plurality of upstanding pins 22 on the upper portionthereof preferably positioned diametrically opposed to each other and inspaced relation to the axis of the spool.

A propeller or projectile member 23 is provided with an axial opening 24for loosely facilitate the winding of the string 20 about i the spool15, the handle 10 may be squeezed so as to laterally move the stopmember 18 so as to hold the spool 15 against movement on the shaft 13.The outer end portion of the flexible member 20, which is provided withan apertured bead or the like 26, may be pulled horizontally oroutwardly thereby turning the spool 15 and the speed of the spool willcause the propeller or helicopter 23 to rotate, and when the propellerrotates .at a sufficiently rapid rate it will rise upwardly from thepins :22 and off of the axial shaft member 13 and spin around in theair.

In the construction of the device, the handie member 10 and the axialshaft 13 may be constructed integrally with each other and constructedof a substantially resilient Wire member.

It will, of course, be understood that various changes and modificationsmay be made in the details of construction and design of the abovespecifically described embodiment of the invention without departingfrom the spirit thereof, such changes and modifications being restrictedonly by the scope of the following claim.

What is claimed is A toy of the character described comprising aresilient looped handle member, a shaft outstanding from said handle, apulley loose- 1y mounted on said shaft, said pulley having a restrictedlower end portion, said pulley also having an annular grooveintermediate the pulley and said restricted lower end portion, stopmeans mounted on said handle and engaging said pulley in said groovedportion, a plurality of diametrically spaced pins mounted on the upperend of said pulley, a flexible member engaging said pulley, and apropeller loosely engaging said upstanding pins on said pulley andadapted for rotation thereby.
